Prendergast has penned a one-year contract at Bloomfield Road, with a 12-month extension option also attached to the deal.
Renowned as one of the best wide players outside the Football League, Pool have paid an undisclosed fee for Prendergast, although it is thought that Stanley accepted less than the £20,000 offer Bristol Rovers had turned down for the former York City man last term.
The 27-year-old impressed during the recent tour of Scotland, scoring in the opening game at Keith, and adds some natural width to Hendry’s thin squad.
